A simple validation package based on Valitron.

Installation

Install the package using Composer:

$ composer require rougin/validia

Basic usage

Create a class that extends to Check class:

use Rougin\Validia\Check;

class UserCheck extends Check
{
    protected $labels =
    [
        'age' => 'Age',
        'email' => 'Email',
        'name' => 'Name',
    ];

    protected $rules =
    [
        'age' => 'required|numeric',
        'email' => 'required|email',
        'name' => 'required',
    ];
}

Once created, submit the data to the said class for validation:

$check = new UserCheck;

$data = /* e.g., data from request */;

if ($check->valid($data))
{
    // $data passed from validation
}
else
{
    // Get the available errors ---
    $errors = $check->errors();
    // ----------------------------

    // Or get the first error only ---
    echo $check->firstError();
    // -------------------------------
}

NOTE: Custom conditions for labels and rules is possible using the labels and rules methods:

use Rougin\Validia\Check;

class UserCheck extends Check
{
    public function labels()
    {
        // Add conditions to custom labels here ---
        // ----------------------------------------

        return $this->labels;
    }

    public function rules($data)
    {
        // Add conditions to custom rules here ---
        // ---------------------------------------

        return $this->rules;
    }
}

If using data from psr/http-message, kindly use the Request class instead and add aliases under alias if necessary:

use Rougin\Validia\Request;

class UserCheck extends Request
{
    protected $alias =
    [
        'name' => 'username',
        'email' => 'email_add',
        'age' => 'new_age',
    ];
}

$check = new UserCheck;

// Should return ServerRequestInterface ---
$request = Http::getServerRequest();
// ----------------------------------------

// Checks against data from "getQueryParams" ---
if ($check->isParamsValid($request))
{
}
// ---------------------------------------------

// Checks against data from "getParsedBody" ---
if ($check->isParsedValid($request))
{
}
// --------------------------------------------

When extending from the Request class, kindly add the setAlias method when overriding the valid method to apply the aliases defined in the specified class:

use Rougin\Validia\Check;

class UserCheck extends Request
{
    // ...

    public function valid($data = null)
    {
        // Always include if has aliases defined ---
        $data = $this->setAlias($data);
        // -----------------------------------------

        $valid = parent::valid($data);

        if (! $valid) return $valid;

        // Add extra conditions here ---
        // -----------------------------

        return count($this->errors) === 0;
    }
}

NOTE: If an alias is specified, the aliases will be used in searching for the said fields from ServerRequestInterface.
